IMPROVEMENT IN GAS-BURNERS.

Specilicationforming part of Letters Patent No. 75,871, dated June 16, 186B.

To all whom it may concern.-

Be it known that I, SAMUEL GARDINER, Jr.,

of New York city, and county of New York, j

in the State of New York, have invented a certain newand useful Improved Self-Li ghtin g Gas-Burner; and I do hereby declare the following to be afu1l,clear, and exact description of the same, referencebein g had to the accompanying drawings, which form a part of this specication.

My invention consists, iirst, in combining a platinum coil or its equivalent with a gals`V burner in such a manner thatit will ettect the Y combustion of a slight leakof gas and retain suiiicient heat to reignite the gas if blown out; second, in the combination of a hood or cap with a platinum` coil or its equivalent applied within said hood or cap.

In the drawings, Figure lis a perspective view of a gas-burner illustrating myinvention.

rated at b b for the admission of air to aid combustion. Within the upper end ofthe hood I placca coil, c, of platinum wire or any other metallic or any other body of suitable charaoter and-construction to adapt it when once heated by the dame to retain and communicate sufficient heat to reignite the gas after vit has been extingushed.

In order the more eii'ectually to retain the heat in the platinum coil c or its equivalent, I

prefer'to form the key D with a very small groove,.d, so as when the main supply of gas is turned oii to permit a slight escape of gas, which will burn in an invisible flame in contactV with the coil. The result is that after the. gas has been turned oii for an indefinite period, when it is again turned on the gas by coming in contact with the hot platinum coil will almost instantly rcheat it to redness, and there-l by will be ignited.

VThe invention is also very valuable in causing .the instant relighting of the gas in the event of it being extinguished by wind, or from any cause by ignorance, carelessness, or accident,

without being turned off.

The cap or hood B, by causing a forced current of heated air and concentrating itin contact with the gas, causes the more perfect com'- bustion of the latter and increases the inten.. sity of the light.

` The employment of the non-corrosive tip is of manifest advantage where a small llame is' kept constantly burning.

Having thus described myinvention, the-fol V lowing is what I claim as new and desire-to secure by Letters Patent: i l

1. The combination of the coil o with a key,

D, formed with one or more-notches, apertures,

. or grooves, as at d, so as to permit a slight leakage of gas when the main supply is turned oft', as shown and described..

2. The combination of the coilc orits 4equivalent with the hood or cap B,substantiaflly as and for the purposes specified.
